[EN] In the last decades there have been an increasing interest in improving the accuracy of spacecraft navigation and trajectory data. In the course of this plan some anomalies have been found that cannot, in principle, ...
[EN] The flyby anomaly is a persistent riddle in astrodynamics.
Orbital analysis in several flybys of the Earth
since the Galileo spacecraft flyby of the Earth in 1990 have
shown that the asymptotic post-encounter velocity ...
[EN] Gravity assist manoeuvres are one of the most successful techniques in astrodynamics. In these trajectories the spacecraft comes very
close to the surface of the Earth, or other Solar system planets or moons, and, as ...
In the last two decades an anomalous variation in the asymptotic velocity of spacecraft performing a flyby manoeuvre around
Earth has been discovered through careful Doppler tracking and orbital analysis. No viable ...
[EN] The flyby anomaly is the unexpected variation of the asymptotic post-encounter velocity of a spacecraft with respect to the pre-encounter velocity as it performs a slingshot manoeuvre. This effect has been detected ...
